The FDR country of origin tells you that it was made some time before October 1990.

Of course! Thanks for pointing that out. Totally missed that.

Btw Catlabs says the following about the revisions. But none of their numbers match this unit.

BULLETIN # B019

Rotation Motor Upgrades for the CPP-2 and the CPA-2 Processors

Introduction

Newer systems, like the 3000 series EXPERT Drums, require increased strength in the rotation motor circuit. This extra load can make the rotation speed of the tank or drum sluggish. The 3000 series EXPERT Drums create the heaviest possible load for the rotation motor circuit.

Beginning production of the CPP and CPA had a single-bearing rotation motor.

CPP Serial # ARXXXX-10593

CPA Serial # ARXXXX-10312

1st Upgrade: The single-bearing rotation motor was replaced by a double-bearing rotation motor.

CPP Serial # 10594-20455

CPA Serial # 10313-13309

2nd Upgrade: The rotation motor circuit was strengthened to accommodate larger loads, that is, 3000 series EXPERT Drums.

CPP Serial # 20456-21999

CPA Serial # 13310-21999

3rd Upgrade: A stronger rotation motor (the same as in the ATLs) was introduced and the rotation-motor circuit was strengthened to accommodate the new motor.

CPP Serial # 22000-present

CPA Serial # 22000-present

Can anyone help me identify this version?

 

Standard calibration distances start at infinity, then at 25 feet/7.62 meter, 15 feet/‪4.572‬ meter, 6 feet/‪1.8288‬ meter then go back to infinity and recheck/adjust until all focused distanced from infinity to the lens close focus distance is correct.

I also have a Konica Pearl with focus issues. I’ve followed your advice. When it comes to near and far focus though what I the method in general terms of getting near and far objects in focus. I can set the infinity focus. The near focus appears to be good. The mid focus seems a bit out.
